[gdal-dev] Transformation methods & parameters (OGRCoordinateTransformation)

2016-03-19 Thread César Martínez
Hi, we are evaluating using Gdal/OGR in order to manage CRSs and transformations on a project. I have read the OGR Projections Tutorial [1] and also had a look to the OGRSpatialReference & OGRCoordinateTransformation API. However, I have not found a simple way to get a list of available transforma

Thanks André, datum_shift.csv is (partially) what I was looking for. I see however that EPSG:15933 transformation operation is missing on that list (which in this Spanish example is usually the most accurate one), maybe because it uses the NTv2 method. In any case, how can I use the datum_shift.c

Hi Jürgen, There is several problems with libdxfrw: 1. The library have GPLv2 license which is incompatible with GDAL X/MIT 2. The library support only DWG from r14 to the last 2003 version 3. This is third party dependency for GDAL. 4. There is already the DXF driver in GDAL. The GPLv2 is ok fo
